The present invention is based on the identification of a cohort of polyurethane block copolymers that are particularly suited for use in pharmaceutical polymeric drug-device units and which offer improved control of drug release. In particular, there is provided a polymeric drug-device unit comprising a polyurethane block copolymer obtainable by reacting together a poly(alkylene oxide); a difunctional compound; a difunctional isocyanate; and optionally a block copolymer comprising poly(alkylene oxide) blocks; and quinagolide as a pharmaceutically active agent. The drug-device units may find application in the treatment and/or prevention of endometriosis.

The present invention generally relates to compositions and methods for treatment and prevention of vaginal infections. More particularly, the present invention relates to compositions including creatinine, such as protonated creatinine or creatinine salts, and optionally one or more weak acids, such as boric acid. The disclosed compositions may be used to treat and/or prevent a vaginal infection, such as bacterial vaginosis, to prevent recurrence of a vaginal infection, to treat and/or prevent a sexually transmitted disease (STD) or sexually transmitted infection (STI), and reduce the incidence and/or risk of a subject transmitting a STI or STD.

The present invention provides compositions for the prevention and treatment of genital herpes, comprising nucleoside modified mRNAs that encode herpes simplex virus (HSV) glycoproteins, including those involved in virus entry and immune evasion, and methods of use thereof.

An intravaginal drug delivery device comprising: a drug delivery device, and a therapeutically effective amount of a single active agent that is therapeutically effective for the treatment of endometriosis, wherein the drug delivery device delivers the single active agent directly to endometrial implants in women diagnosed with endometriosis, wherein the single active agent is selected from the group consisting of mifepristone and metabolites thereof.

The present invention relates to a vaginal sustained-release drug delivery system for luteal support and a method for preparation and use thereof. The vaginal sustained-release drug delivery system for luteal support is a progesterone depot-type vaginal ring having a bilayer structure of a core layer and a film layer enclosing the core layer, wherein the core layer is composed of a solid scaffold carrier of medical EVA containing a drug uniformly dispersed therein, and the film layer is composed of a medical EVA material containing no drug. The vaginal sustained-release drug delivery system for luteal support according to the present invention can be used for assisted reproduction and for treatment of functional uterine bleeding, premenstrual syndrome and the like due to luteal phase defect with a significantly improved therapeutic effect.

Geometrically complex intravaginal rings, systems and methods of making the same are provided herein. Disclosed herein are geometrically complex intravaginal rings with tunable and enhanced drug release, which in some embodiments can be fabricated by 3D printing technologies. The disclosed IVRs include a ring structure comprising a plurality of unit cells or macroscopic and/or microscopic architecture, which can be tuned to control the loading capacity of an active compound within the IVR, the diffusion of an active compound from the IVR, the surface area of the IVR, and/or the mechanical properties of the IVR. The disclosed geometrically complex IVRs can provide superior control over drug loading and drug release compared to conventional IVRs fabricated by injection molding or hot-melt extrusion.

The present invention relates generally to suppositories that release nitric oxide, and methods of using the same.

Drug Delivery Silicone Composition to improve Active ingredient Elution. The invention relates to a new curable liquid silicone rubber composition which after curing provides a silicone elastomer useful as a drug delivery device comprising an active pharmaceutical ingredient (API) having terminal alkene, alkyne or carbonyl functionalities exhibiting an increased recovery of the active pharmaceutical ingredient.

An intravaginal ring device is provided. The core includes a core polymer matrix within which is dispersed a therapeutic agent comprising one or more aromatase inhibitors. The core polymer matrix contains an ethylene vinyl acetate copolymer. The ethylene vinyl acetate copolymer has a vinyl acetate content of from about 10 wt. % to about 60 wt. % and/or a melting temperature of from about 40° C. to about 120° C. as determined in accordance with ASTM D3418-15.

The present invention relates to methods and compositions for increasing reproduction performance in non-human mammals using recombinant luteinizing hormone (rLH) in a low dose. The invention also relates to methods for increasing follicle growth rates at later stages of synchronization programs, improving ovulation results, corpus luteum (CL) development after ovulation, or pregnancies in non-human mammal using rLH in a low dose. The invention is preferably used in ungulates such as bovine, in association to synchronization programs for timed ovulation.
